.SH DESCRIPTION
.sp
\fBceph\-conf\fP is a utility for getting information about a ceph
configuration file. As with most Ceph programs, you can specify which
Ceph configuration file to use with the \fB\-c\fP flag.
.SH ACTIONS
.sp
\fBceph\-conf\fP performs one of the following actions:
.INDENT 0.0
.TP
.B \-L, \-\-list\-all\-sections
list all sections in the configuration file.
.UNINDENT
.INDENT 0.0
.TP
.B \-l, \-\-list\-sections *prefix*
list the sections with the given \fIprefix\fP\&. For example, \fB\-\-list\-sections mon\fP
would list all sections beginning with \fBmon\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-lookup *key*
search and print the specified configuration setting. Note:  \fB\-\-lookup\fP is
the default action. If no other actions are given on the command line, we will
default to doing a lookup.
.UNINDENT
.INDENT 0.0
.TP
.B \-h, \-\-help
print a summary of usage.
.UNINDENT
.SH OPTIONS
.INDENT 0.0
.TP
.B \-c *conffile*
the Ceph configuration file.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-filter\-key *key*
filter section list to only include sections with given \fIkey\fP defined.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-filter\-key\-value *key* \(ga\(ga=\(ga\(ga *value*
filter section list to only include sections with given \fIkey\fP/\fIvalue\fP pair.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-name *type.id*
the Ceph name in which the sections are searched (default \(aqclient.admin\(aq).
For example, if we specify \fB\-\-name osd.0\fP, the following sections will be
searched: [osd.0], [osd], [global]
.UNINDENT
.INDENT 0.0
.TP
.B \-r, \-\-resolve\-search
search for the first file that exists and can be opened in the resulted
comma delimited search list.
.UNINDENT
.INDENT 0.0
.TP
.B \-s, \-\-section
additional sections to search.  These additional sections will be searched
before the sections that would normally be searched. As always, the first
matching entry we find will be returned.
.UNINDENT
